The DFI Microbiome Metagenomics Facility (MMF) provides bacterial 16S ribosomal RNA gene and shotgun metagenomic sequence analyses on intestinal contents and other samples containing complex microbial populations. The MMF works with investigators to analyze microbiota sequence data from experimental and clinical samples. Analysis tools are available to classify bacterial sequences down to the genus level (and to the species level when possible) to determine both community membership and structure. Analyses include graphic visualization of the bacterial composition of individual samples and determination of microbial population diversity within and between samples.
